Safety:
 A scale-free generator reduces the danger of damage due to low pressure.
 Make sure that the suction panel and the hanging rack are installed and
fastened according to instructions after descaling
 Flush all descaling residue thoroughly out of the steam generator. Residue
can lead to far reaching damage (An error reading on the water level probe due to
foaming residue in the steam generator).
Attention Unit Damage: i.e. Heating elements burning out.
Attention Health Damage: Water sprays or foaming are able to run out of the
steam generator into the oven onto the food.
Attention:
 Descaler can never be heated
 Remove thoroughly all over flow descaler with a lot of water.
 Vapors can cause irritation! Ensure adequate airing!!
 Do not inhale spray mist or vapors!
Notice: Descaling solution
 Vinegar or citrus acid are biodegradable.
 Otherwise use only recommended Convotherm Descaling solutions
 CONVOCal for normal scaling (with anti-foaming)
 CONVOCal forte  the stronger descaler for heavy scaling build up (with anti-
foaming)
 For heavy scaling, remove the immersion heating element and remove the scaling
mechanically before chemical removal begins.

* Depending on the size of the unit the steam generator pump has to be switched on
one or more times, until the steam generator is empty. This is why it is
recommended to remain by the unit during the pumping out phase in order to pay
attention to the pumping noise. This noise changes when the steam generator is
empty. If the steam generator is empty do not switch the pump on again!
2. Unit main power supply must be disconnected with an all-pole isolation switch
and ensured against switching on again! (If the fan is running wait until it
comes to a full stop!)
3. Swing suction panel out.
